Vibrating Wire Uplift Pressure SystemModel No. TES-PU-20V

Product Description

TES-PU-20V is a vibrating wire uplift pressure measurement

system that uses a vibrating wire pressure sensor. It is designed

for monitoring uplift pressure of water in foundation of dams

and concrete structures. The sensor is similar to TES-PP-30V

except that instead of !lter, a 25 mm BSP adaptor is provided

for pipe connection. A perforated/non-perforated pipe is

inserted in the borehole, at the top of which TES-PU-20V is

attached through valves and !ttings.

Bourdon Gage Type Uplift Pressure SystemModel No. TES-PU-20G

Product Description

TES-PU-20G uplift pressure measurement system is similar to the above excepting that it incorporates a

bourdon gage with dial readout instead of vibrating wire pressure cell that requires an electronic

readout.
